概率与统计这部分内容在高考中处于相对重要的位置,每年都会有一道解答题,难度中等,命题方向从前几年的只考离散型随机变量的分布列变化为近几年的概率与统计的“多点开花”:第一类命题直接考查二项分布和超几何分布;第二类是借用二项分布和超几何分布的计算概率的思想,但题目所研究的随机变量并 Probability and Statistics This part of the entrance examination is in a relatively important position, every year there will be a solution to the question, the difficulty is moderate, the proposition direction from the previous few years only discrete variable random variable distribution column changes in recent years, the probability and statistics The first type of proposition directly examines the binomial distribution and the hypergeometric distribution. The second type refers to the idea of ​​borrowing the calculation probability of the binomial distribution and the hypergeometric distribution. However, the random variables studied by the subject and
